The halfâequivalence point of a titration occurs half way to the equivalence point, where half of the analyte has reacted to form its conjugate, and the other half still remains unreacted. If 0.440 moles of a monoprotic weak acid ( K a = 8.3 Ă 10 â 5 ) is titrated with NaOH , what is the pH of the solution at the halfâequivalence point?

Phosphoric acid is a triprotic acid ( =6.9Ă10â3 , =6.2Ă10â8 , and =4.8Ă10â13 ). to find the ph of a buffer composed of h2poâ4(aq) and hpo2â4(aq) , which p value should be used in the hendersonâhasselbalch equation? p k a1 = 2.16 p k a2 = 7.21 p k a3 = 12.32 calculate the ph of a buffer solution obtained by dissolving 18.0 18.0 g of kh2po4(s) kh 2 po 4 ( s ) and 33.0 33.0 g of na2hpo4(s) na 2 hpo 4 ( s ) in water and then diluting to 1.00 l.
